Broken "light well" bolt installing UnderCover Tonneau

So for my first mod to my 2014 Double Cab Prerunner (besides Weathertech floormats) I decided to get an UnderCover Tonneau. All was going well until one of the "light well" bolts broke off while attempting to install the rear mounting bracket for the undercover. The bolt I am referring to is the one on page 6 of the Instructions (pictures C & D). The bolt broke pretty close to the head so I'm now trying to figure out how I'm going to get it out

Anyone have a suggestion? Also, does anyone know what the precise name of this bolt is or a part number so that I can get a replacement?

Thanks!

 

1.) Center punch the bolt that is still in the hole.

2.) Get a small left hand drill bit and drill a hole in the center. Go slow and easy, let the drill do the work. Note: this may back it out when the bit starts cutting.

3.) If drilling doesn't back out the remains, Get an easy out and use it to remove the bolt.

Use one on the other side of the truck to figure out the size. Remove it and go to the hardware store.

 

Thanks! I'll give it a go.

 

Remember to just go slow and take your time.

 

Update: Bolt is out and the Undercover Tonneau is installed!

Thanks again!
